DESCRIPTION OF THE INVENTION

(12) The invention refers to bolt to pin lock with interchangeable combination that can be used mainly in gates, cold storage rooms, commercial vehicles, containers, wagons manufacturing facilities, and doors. The mechanism includes a main metal shaft, a through bolt with a long ridge as a key and discontinuous in some parts according to the need; on the metal shaft includes a few overlapping pulley wheels and interchangeable in their position, thus allowing to choose the desired combination according to printed numbers in the pulley wheels (from 0 to 9) only moving and using the axis on its shaft.

(13) Therefore, the bolt mechanism allows to program the numerical combination of either 1, 2, 3 or 4-digit, as in this case, according to the number of pulley wheels that have the device.

(14) The mechanism is complemented by a box base, a cover, one end or handle, and other end or latch locks.

(15) The mechanism is described in terms of its parts in the following manner:

(16) A shaft (2) has a round section with a long edge pin (2.1) on its edge. The pin (2.1) includes a discontinuous section (2.2) in some parts according to the need. An internal roller (3) is inserted on the shaft (2). The internal roller (3) having an external face (3.1), an internal face (3.2) with a borehole including a groove (3.3) to be secured in position on the ridge of the shaft (2).

(17) An external roller (4) includes an internal face (4.1) and a segmented external face (4.4). Slots 4.2 separate adjacent segments of the external face that leave his position fixed and not be able to move. Each segmented external face 4.4 includes printed numbers (4.3) from 0-9.

(18) The internal roller (3) and the external roller have a decagonal faceted edge (3.1) which allows therefore to set 10 different positions.). t

(19) The bolt includes a housing (1) that covers the mechanism of the weather inclemency. The housing (1) includes a base end (1.1) and a top end (1.2). A support (9) is placed on an extension (1.4) of the base end (1.1). The support (9) has a pivoting movement with the locking device (8) or with the bar (11) depending on the type of gate. The housing (1) includes a a number of cuts (1.4.1), (1.4.2), (1.4.3) or (1.4.4) depending on the number of rollers proposed for the number of combinations that have the bolt; The cuts form windows that allow viewing and modifying the positions of the external roller g device (4). Inside the housing (1) there are dividing walls (1.3) that are crossed by the main shaft (2). The shaft (2) has at one end a lever command (13) and the other end acts to lock and unlock latch of the lock. In the case of being used in gates, it is responsible for triggering the pivot system (10) that fixed the locking device (8) to the post (11) at the time of lock. In the case of guillotine type gates (11 is positioned it within the post (13). The main shaft (2) is fixed with the triggering the pivot system (10) which triggers the guillotine and locked in that is a support of the guillotine with a U shape and separate from the bolt. These elements both pole with the wheel, or the support with the guillotine are ultimately those who lock or unlock the aperture of the lock and both are powered by the bolt to pin lock with interchangeable combination.

(20) On the shaft (2) are placed overlapping or rollers (3, 4) that are interconnected between them. The external faces (3.1) of the internal roller (3) are interconnected with the internal face (4.1) of the external roller. The position between the rollers can be interchangeable, thus allowing choosing the combination desired, according to the number of faces (4.4) of the external roller (4) and on the basis of printed numbers (4.3) on the faces (4.4) of the external roller.

(21) When the shaft (2) is located in the correct position, i.e. the edge pin (2.1) coincides with the guides (3.3) of the rollers (3). The shaft may slip and unlocks the bolt, ring or guillotine as the case may be. The correct location of the shaft with the roller corresponds to a single possible combination that has been previously adopted. The spaces (2.2) are spaces of free spins of the rollers and have the measurement of the width of the pulley wheels or rollers (3). When groove (3.3) of the roller (3) corresponds to the key (2.1) allows the sliding of the main axis for the opening or closing of the bolt lock, and when the spaces do not match (2.2) with (3.3), the bolt lock is unable to open or close. The straps (6), when it is positioned in the slots (4.2), allows an individual roller locking preventing these are under control, the straps (6) have a base (6.1) that are anchored in the housing (1). For the case that the bolt to pin with interchangeable combination is used both in type lock gates with ring or guillotine type, the base (1.4) on the box base, is extended up to the end (9) which pivots the ring (8) as the guillotine (11) and that through a cardan system (10) is fixed to the end of the shaft (2) to trigger the closing or opening of the lock type guillotine (11) or ring (8).
